After collaborating for Brett IPA earlier in the year, Wicked Weed Brewing and New Belgium Brewing will be releasing a followup in November.

Named Tributary, the new beer is described as an imperial brett saison brewed with sugar beets as well as water, malt, and yeast from both brewery’s home states of Colorado and North Carolina and experimental, yet-to-be named hop variety. Only 3,200 bottles are being released, with the beer listed at 8.8 percent ABV.

“In an effort to protect our most essential local ingredient, a portion of bottle sales will go towards supporting the endeavors of the Riverkeepers of WNCA who work to ensure the longevity of our watershed,” says a post on Wicked Weed’s Instagram feed.

This is the second collaboration for both breweries after the release of Brett IPA, which was brewed in September of last year using spelt from Asheville’s Riverbend Malt House along with a brettanomyces strain and a developmental hop variety from New Belgium. Brett IPA was brewed in Fort Collins, Colo. at New Belgium Brewing while Tributary is being brewed in Asheville, N.C. at Wicked Weed Brewing.

Tributary will be released in 500-ml bottles at an event on Nov. 15 at the Funkatorium located in Asheville, N.C., and will only be distributed within that state. Wicked Weed Brewing told Tenemu that pricing has yet to be determined.
